duri punggung lunak (Keseluruhan (total)) : 15 - 17; Sirip dubur lunak: 14 - 15; vertebrata, bertulang belakang: 30 - 35. Males with a less prominent notch in dorsal fin; no irregular black spots on sides of body; a gray cast superimposed on gold body and gray fins. Head wedged shaped; upturned lips; proportionately larger head and orbit. Tendency to fewer lateral scales, predorsal scales and vertebrae. Male with fins larger, especially dorsal and anal fins; greater prepelvic length, head and body depths; first 6 anal-fin rays small folding into fleshy dermal pocket supported by 7th ray; dorsal fin notched, first 4-5 rays separated slightly from the rest.
Body shape (shape guide): short and / or deep; Cross section: oval.
An experimental fish. Pinnate diatoms (largely benthic), filamentous algae indicate that this species grazes rocks and plant surfaces along or near the bottom (Ref. 29410). Migratory behaviour is undetermined (Ref. 126106).
